The Classroom Attitude Observational Schedule (CAOS) is designed to detect pattern shifts in a classroom during the absence of controlling adults. It is concerned with the independent learner who will continue school related tasks in a socially acceptable manner without supervision. The CAOS recording form notes activities and inappropriate behaviors as they occur; ideally the children should be controlled by their own interests in the activities and materials in the classroom. CAOS was field tested in schools using the Tucson Early Education Model (TEEM), a program offering a balanced program of child selected and teacher assigned activities, and results, presented here in graphs, were relayed to Follow Through Directors and TEEM field staff so that attention may be given to those aspects of the TEEM touched by CAOS and the system may be further refined.
